    • Massive cushioning meets surprising agility — perfect for long runs and high-mileage days
The SC Trainer v3 has quickly become my go-to for long runs and high-volume training. The FuelCell midsole paired with the Energy Arc plate delivers an ultra-cushioned, yet responsive ride that feels smooth and efficient mile after mile. Despite the high stack, the shoe doesn’t feel unstable or clunky. On the contrary — it rolls beautifully and actually feels lighter than it looks. I’ve used them for long runs, progression runs, and even some steady tempos, and they handle all of that with ease. Fit is true to size, and the upper is soft, breathable, and secure without being overbuilt. One thing I really appreciate is that you get the feel of a super shoe but with daily durability — ideal for those who want plated performance without burning through race-day shoes in training. If you want comfort, bounce, and protection for long efforts, this is a top-tier trainer. __ __ Los SC Trainer v3 se han convertido en mis favoritos para fondos largos y entrenamientos de alto kilometraje. La combinación del FuelCell con la placa Energy Arc ofrece una pisada ultra cómoda pero con buena respuesta, que se siente fluida y eficiente kilómetro tras kilómetro. A pesar de tener una suela altísima, no se sienten inestables ni torpes. Al contrario, el “rocker” es muy suave y hasta parecen más ligeros de lo que se ven. Los he usado para fondos tranquilos, progresivos e incluso ritmos controlados, y se comportan genial en todo. Tallan normal, y el upper es cómodo, transpirable y firme sin apretar. Lo que más me gusta es que ofrecen una sensación de “superzapatilla” sin tener que sacrificar durabilidad, como pasa con los modelos de competición. Si buscas comodidad, rebote y protección para tus tiradas largas, estos SC Trainer v3 están en lo más alto. ... show more

    • Great quality
Size: 7 Wide Color: Angora/Hot Mango/Black
I got the 8.5 wide and by far the best running shoes I have. No more knee pain. It’s light weight and it fits just right. I wish they made them in solid black.

    • Awesome trainers!
Size: 13 Color: White/Cyber Jade
This is a fantastic pair of running shoes. I have tested them in all sorts of different weathers and they have yet to disappoint. Great comfort and cushioning. Initially I found them to be a little bouncy, but eventually I get used to it. Highly recommend them.

    • Very comfortable and good for speed training.
Size: 10.5 Wide Color: Angora/Hot Mango/Black
Fantastic all around running shoe. I have wide feet and these are a perfect fit with a very roomy toe box. Plenty of cushion and well balanced. The only negative thing I can say about the shoe and it’s fairly minor but there is a little bit of movement in the heel area, as it is designed a little bit slicker on the inside than I would prefer. I just have to lace them extra tight and it’s all good. I will definitely be buying these again when I wear this current pair out. I’m hoping I can get a couple hundred miles out of them. ... show more

    • Great trainer
Size: 10.5 Color: Melon Water/Clay Ash/White
I have finally settled on a daily trainer. This shoe has a good balance of weight and comfort. I did my long run on Sunday and changed shoes in the middle to compare the New Balance vs the Brooks Glycerin. The Brooks are comfortable but are definitely less responsive on my push off. The carbon-plated race version, the NB V5 Elite is a fine shoe, and many people are using them for triathlon. Great if you have a mid foot strike. Nike’s (Alpha Fly) force me personally to fore-foot strike which helps increase my cadence. So the jury is still out on my race shoe. BTW: The speed version of this shoe, NB Pacer, is excellent. Light and fast. I use it for my tempo runs which last for up to 10 miles. For a super light shoe I have no discomfort. Very surprised! ... show more

    • Amazing so far
Size: 14 Color: Urgent Red/Sea Salt/Black
Pretty nice. They run a bit large. I normally wear size 14 men in Nikes and adidas but these run about half size large but I wear two sock layers to mitigate that issue. There very stable and lightweight and comfortable. I have wide flat feet and the normal size fits fine. Often times the wide version is too large and bulky. Good price. Nice bright color. Lovely. I’m a heavy runner (240-245) lbs muscular build and these handle my size like a champ. 6’3” I just wish they made 13.5 size in men. Then they’d be perfect. ... show more

    • Great Carbon Plate Shoe, Great Price
Size: 10.5 Color: Grey Matter/Mint Flash/Silver Metallic
Love the shoe through 12-13 miles ran. Toe box is a bit wider than other brands I’ve worn, which is a plus. I seen online some people were sizing up a 1/2 size on theirs, for me 10.5 fit true & I am generally in between 10.5-11.0 in most brands. Positives: - responsive bounce - wide toe box - wide heel - relatively stable Negatives: - underwhelming cushion - shoe laces seem like they will wear out quick - a bit heavy ... show more
